Ackerman's Rush to Judgment, Part 2

To follow up my first post on Bruce Ackerman's and Oona Hathaway's op-ed, I'd also note that he and his co-author presume that Section 2(a)(2), authorizing military force to "enforce all relevant United Nations Security Council Resolutions regarding Iraq," referred only to subsequent U.N. authorizations pertaining to Iraq. Of course, Congress referred to several prior U.N. resolutions pertaining to Iraq, too. 

Isn't it curious that Ackerman and Hathaway read the U.N.-resolution subsection as applying  to future U.N. resolutions, while they read the national-security-threat subsection as applying only to pre-2003 threats?
